I traded amzn today, and was very impressed. I could really move 5-8k like buttah... I think it was easier than with fractions cause on fractions, I'd dump 3k and the bid would drop a teeny, and I'd dump another 4k and the bid would drop again. Here, since everyone isn't lined up, you can just dump 2k, wait 10 secs for the bids to build and then swipe down.. and I never swiped more than .03 down. I think it was much more liquid, but I never dealt with mm execution. Just island and Inca i think.
